SPECTACLES.

SPECIFICATION forming part of Letters Patent No. 453,327, dated June 2,1891.

Application filed February 9, 1891. Serial No. 380,725. (No model.)

To all whom it may concern.-

Be it known that we, ALFRED J. PARKER, a subject of the Queen of GreatBritain, residing at the city and State of New York, and GEORGE M.GUERRANT, a citizen of the United States, residing at the city and Stateof New York, have invented an Improvement in Spectacles, of which thefollowing isaspecification.

Spectacles having two temple-bows are difficult to place in positionwithout 'the use of both hands, and with business men, especially publicspeakers, this is inconvenient, because the left hand is often employedin holding a book or paper at a time when it becomes necessary to placethe spectacles in position. \Vith eyeglasses the spring employed at thenose-bow for causing the glasses to grasp the nose cannot always berelied upon for holding the glasses in position, and frequently the clipor holding device upon the nose is disagreeable and the skin becomesdisfigured.

The present improvement is made to facilitate the placing of thespectacles in'position by one hand and to insure greater stability ofthe spectacles under the ordinary circumstances of use.

In the drawings, Figure 1 is a perspective view illustrating theimproved spectacles and their mode of use. Fig. 2 is a plan view; andFig. 3 is a rear View with the temple-bow folded.

The glasses A are of any desired size or shape, provided with metalrims, and the nosebow Bis between the same and sufficiently rigid not tobe bent or sprung under the ordinary conditions of use. It is preferableto unite the rims of the glasses and the nosebow by the lugs andclamping-screws 2 at the junctions of the rims with the nose-bow, inorder that the rim of the left glass may not have anyprojection exceptwhere it is united to the nose-bow; and at the outer edge of the rim atthe right side of the eyeglasses is a hand-piece or loop 0, that isadapted to being grasped by the thumb and finger in placing the glassesin position or removing them.

The temple-bow D is hinged at 3 to the spectacle-rim or hand-piece, andthis templebow D is made with a cross-piece 4, preferably in the form ofan open loop, and the side next the head is suificiently concave tocause the ends of the cross-piece to bear against the side of the head,and the length of the temple bow is to be such that the lower end ofthis cross-piece 4 passes behind the' ear, and the parts are to be bentso as to adapt the spectacles to the person wearing them, and whenapplied in position the weight of the glasses rests principally by thebow B upon the nose, and the glasses cannot slide forward because thecross-piece 4 is hooked in behind the ear, and the spectacles aremaintained in a horizontal position and in the line of vision by thecross-piece 4 resting against the side of the head. Hence suchspectacles cannot. tip or become misplaced easily, and it will beapparent that the spectacles can be put in position or removed by onehand, because by grasping the handpiece 0 the spectacles can be placedupon the nose and the temple-bow moved into position for the cross-piece& to hook behind the ear, and the spectacles can be removed by thereverse operation, which is a great convenience over the spectacleshaving two temple-bows and requiring the use of both hands in puttingthem into position.

In order to adapt these spectacles to different persons they aresometimes made with an extension temple-bow-that is to say, thetemple-bow is made of two pieces, with loops 5 and 6 at the respectiveends, through which the adjacentpiece of the temple-bow passes, as seenin Fig. 3-similar to the ordinaryextension-bow,andtheseeXtension-piecesshould slide with sufficientfriction to prevent them becoming displaced under the ordinarycircumstances of use.
